The Commodore Amiga is dead.
It is as dead as OS/2, sure people may program for it and it may be useful for many things, but it is dead.
Aros, OS4, Pegasos, and others on the other hand are definitely not dead.
Huh? The Amiga is not dead. Just ask Jens and everyone else still producing relevant and modern hardware for it. The Amiga community certainly isn't dead either. Until there are no longer any sites like this devoted to the Amiga and nobody is talking about or producing any hardware or any software at all, then I'd say the machine and its "spirit" would be dead. But that's not going to happen any time soon. I view the original legacy Amiga gear and these spinoffs as something of a family. Original Amiga computers being the "father or grandfathers", with Aros, Pegasos, MorphOS, A1K, etc. as the children and grandchildren
If your definition of 'dead' reads: "nobody is currently producing actual legacy systems", then yeah - that's obvious. But surely the Amiga is just as or more "alive" than any other vintage or classic computing platform that I'm aware of.
